An unconventional children's film that should spark conversations between adults and kids, this thoughtful and lighthearted romp from Mipo O (21st HKAFF Director in Focus) follows a group of children who set out to change the world. Yuishi develops a crush on a classmate after hearing her impassioned speech about climate change, so he tries to impress her by taking up her cause. Eventually, they turn to mischief in the name of the environment. Eliciting amazingly natural performances from her young cast by shooting at a child's height with free-roaming cameras, O once again proves herself to be a keen and humanistic observer of people, regardless of age.
